Hi
I have some problem with using ADO and InterBase database. I am using ODBC
(Gemini EasySoft) and in both cases there is this problem:

/* part A*/
query->SQL->Text = "SELECT * FROM SysLevels";
q->Open();
int c = q->Fields->FieldByName("id")->AsInteger;
q->Close();

/* part B*/
query->SQL->Text = "INSERT INTO DocFTP (Title, BaseDir)  VALUES
('test','test')";
query->ExecSQL();  /* There is Access Violation error */

If I execute these parts separately, it does work, but when I execute part B
after part A, there is "Access Violation Error"
Could anyone help me? I really don't know how to solve this situation. I
suppose it
could be because of bad implementation of ADO component.
I have been trying others ODBC drivers and OLE DB drivers, but I found only
other problems (typically with Access Violation Error).
I am using:
Borland C++ EnterPrise 5.0 with updatepack1 and ADOupdate.
Interbase 6.0 and InterBase 6.1
patch MDA 2.6

Thanks
